Module setup

Set excitation frequency

The excitation frequency is used to supply the correct frequency for all of the

sensors connected to an LVDT module. Sensors that require different excitation

frequencies require a separate LVDT module or they will not run at optimum

performance. The desired frequency should be obtained from the sensor

manufacturer documentation. LVDT modules are preset to default values. The

excitation frequency must be a value from 3.0 to 50.0 kHz.

To change excitation frequency:

Click inside the Exc. desired (kHz) text field.

Delete the current excitation frequency.

Enter the desired value.

Click the OK button.

A message verifying the action is displayed in the message area.

The Exc. (Vpp) will be updated with the new voltage that is being used in the

module. This value is affected by both the excitation voltage and the excitation

frequency.

Set excitation voltage

The excitation voltage is used to supply the correct voltage for all of the sensors

connected to the module. Sensors that require different excitation voltages require

a separate module or else they will not run at their optimum performance. The

desired voltage should be obtained from the manufacturer of the sensor. LVDT

modules are preset to default values. The excitation voltage must be a value from

1.5 to 5.5 V.

To change excitation voltage:

Click inside the Exc. desired (Vpp) text field.

Delete the current excitation voltage.
